Riya runs around a square field of side 85 m. Ajay runs around a rectangular field with length 180 m and breadth 110 m. Who covers more distance and by how much?
Answers
Answer:-
Given:
Riya runs around a square field of side 85 m and Ajay runs around a rectangular field of length 180 m and breadth 110 m.
We have to find:
Who covers more distance and by how much.
Distance covered is nothing but the perimeter of the square/rectangular field.
Hence,
Distance covered by Riya = perimeter of the square field
We know that,
Perimeter of a square = 4 * length of any side.
Hence,
Distance covered by Riya = 4*85
→ Distance covered by Riya = 340 m
Similarly,
Distance covered by Ajay = Perimeter of the rectangular field
Perimeter of a rectangle = 2(length + breadth).
→ Distance covered by Ajay = 2(180 + 110)
→ Distance covered by Ajay = 2(290)
→ Distance covered by Ajay = 580 m
On comparing the distances covered by both , we can say that Ajay covered more distance.
Now,
Difference between the distances covered = 580 m - 340 m
→ Difference between the distances covered = 240 m
Hence, Ajay covered more distance than Riya by 240 m.
answer:
perimeter of square= 4 *85 =340
340 m
perimeter of rectangle = 180 + 110 divide by 2
290 divide by 2
=145 m
=riya runs more than ajay by =340 - 145 = 95 m
